London, Aug 21 - Pop diva Madonna refused to wear jewellery that her model boyfriend Jesus Luz bought for her birthday.

Jesus, 22, gave the singer a set of South American good-luck bracelets made of thin ribbons that are said to grant the wearer three wishes when they break. He gave it to Madonna on her 51st birthday party Sunday.

But Madonna was quick to tell Jesus she couldn't wear it, reported femalefirst.co.uk.

'Madonna said that although she loved the bracelets, she wouldn't wear them because they clashed with her Kabbalah bracelets. Jesus was crestfallen,' said a source.
